What letter would a chemist use in front of 235 or 238?
U from uranium235U and 238U (recommended); also possible U-235 and U-238 or uranium-235 and uranium-238.
What fuel does a nuclear reactor use?
Uranium-235 in combination with Uranium-238, enriched from natural levels of about 0.7% U-235 to about 5% U-235. There are other configurations, but this is the most common.
What element was used in the atomic bomb dropped on Hiroshima?
Uranium-235 (U-235).
What is the U-235 content of depleted uranium (DU)?
Depleted uranium is uranium with a content of the isotope uranium-235 under 0.7 %. Natural uranium has been processed to change (increase) the concentrations of lighter isotopes, and the "leftovers" are termed depleted uranium. Let's look at this heavy metal and sort things out. Without splitting hairs, the element uranium as it comes out of the ground is almost 99.27% U-238, and about 0.73% U-235. There's also a trace of U-234 in it. The isotope U-235 is the desired one for use in nuclear fuels and in nuclear weapons. Uranium is processed or "enriched" to increase the amount of the lighter isotope in the the finished product. This leaves the rest of the uranium "depleted" of some (or much) of its U-235 (and U-234, for what it's worth). The term depleted uranium is then applied to the remaining uranium.

Used as an explosive ingredient in nuclear weapons?
Uranium isotope U-235

What is a U -235 regulator?
A U 235 Regulator is something used to regulate the combustion of U 235 which is a grade of Uranium. Another grade of Uranium can be used as a regulator for U 235. A suggested grade for regulation is U 238.
Which isotope of uranium hexafluoride gas would be expected to pass through a porous membrane at a greater rate U-235 or U-237?
U-235
An isotope of uranium using nuclide notation?
The chemical symbol of uranium is U.
Are uranium 235 and uranium 238 said to be radioactive molecules since they have the same number of protons but different numbers of neutrons?
No, Uranium-235 and uranium-238 are radioactive, natural isotopes (not molecules, but atoms) of the one and the same element: uranium.Both with 92 protons and 235-92 = 143 neutrons in U-235 but 146 neutrons in U-238.
What are the fertile isotopes of Uranium?
There are many isotopes for uranium, the most abundant of them in nature are:Uranium- 234, having 142 neutron and 92 protonUranium- 235, having 143 neutron and 92 protonUranium- 238, having 146 neutron and 92 protonThe abundance of these three isotopes in natural uranium is:Uranium-234: 0.006 %Uranium-235: 0.720 %Uranium-238: 99.274 %
What is the element uranium used for in warfare?
